They are used for snagging castings and dies (forgings) and materials after they have been cut or welded on stationary and swing frame grinding machines. The grinding operation is hand guided. A high grinding effect is demanded, independent of the surface finish. The operating peripheral speed can be 50, 63 or 80 m/s.

For grinding on stationary grinding machines somewhat softer wheels are used than those applied on swing frame machines. For grinding at operating speeds up to 50 m/s wheels type 1 are used, while for rough grinding (grain size up to 36) wheels type 1AO are applied. Grinding wheels for the use at an operating speed of 63 m/s are designed with a fine grain ring which provides for a higher wheel strength (type 1FK). Wheels with an operating peripheral speed of 80 m/s are reinforced (type 1A), the specifications being 52A16-24M-P6BF05.
